DESCRIPTION
 
SPC-1007 Series polyol is a fully formulated polyol blend developed for spray application of PU rigid foam. The component ratio has been adjusted to make it suitable for use with polyurethane foam spraying machines with a fixed volumetric component ratio of 1-1.2:1. It already contains sufficient quantity of blowing agent HCFC 141b to achieve the foreseen foam density.

When polyol and isocyanate (MDI) are mixed together using suitable foam spray equipment, the resulting foam has a homogenous density. Foams which are allowed to cure for a sufficient time between the layers applied have good skin formation and show good adhesion to the sprayed surface. Special care must be taken the sprayed surfaces are not cold or wet.

It is maily used for the insulation of wall&roof and cold room&container.
